High School: Nussbaum graduated from Eastside Prep, but he was part of the Issaquah High School quartet that won the 200 medley relay with a state record time at the Washington 4A state championships, capping a season in which they also won the district and conference titles while setting records at both levels. That performance added All-American consideration to Nussbaum's already crowded resume of honors, which included three all-conference awards as well as all-state in his senior season. He was able to swim for Issaquah HS because Eastside Prep does not have a varsity swim team.
Club: Nussbaum is a multi-record holder for the Issaquah Swim Team, reaching the Western Zone meet in 2012.
Personal: Nussbaum is the son of Debbie and Charlie Nussbaum, and he has an older sister named Amanda and a brother named Keith. Nussbaum is a pre-major.
